Alternator harness no field power - Dodge Cummins Diesel Forum.

Check Alternator. Even though it is rare, we still recommend you check your alternator. If you have a bad alternator, your coils won't power up at all. Start by checking whether the alternator is even charging or not. Also, try restarting the alternator and check if it is able to restart. Potential damage near or on the alternator can cause.

What Does an Alternator Do? - Firestone Complete Auto Care.

My main question is on the alternator pulley. I understand that it should lock up one way, and spin the other if I put a stick/rod/screwdriver in the alternator to stop it from spinning. Mine locks up one way and spins the other, but it doesn't spin as easily as my idler pulley or tensioner pulley.

Tech Tip: Diagnosing Starter Cranking Problems - Delco Remy.

The alternator that I bought claims to be 1 wire, or self exciting which I have learned that it does not need input current to create a magnetic field. So I have a self exciting 105 amp car alternator, a 12 volt car battery, and all the wire in the world. I also have meters, and a way to spin the alternator shaft at high rpm. Any time you take drag off the engine (AC, for example) you'll save fuel. However no one in their right mind would realistically do it with an alternator since it does so much more than charge the battery when the vehicle is running. You should be able to run the vehicle without a battery if the alternator is working. My guess is your '140 amp' alternator is at fault if its not keeping up with the electrical system at idle that you feel it should be doing. Maybe the internal regulator is bad on the unit. You should consider buying a 94 amp alternator from the local auto store and hook it up to see if it performs as you would expect.

Alternator clutch pulley symptomsProperly diagnose and solve.

A dead car battery is the first sign that something might be wrong with the alternator. If your battery is good, and your alternator isn't working, the battery will still lose its charge because the alternator isn't keeping it charged. So, you'll want to check for the below signs to determine if it's just the battery or if it's the alternator. For all issues, the initial troubleshooting is the same: you start with the batteries. STEP 1 - Begin at the batteries: Charge the batteries and perform battery load test on the battery bank. If the load test fails, then individually test each battery and replace any faulty ones. STEP 2 - Perform a voltage drop test: Once batteries pass muster. If the alt light doesn't come on when the key is first turned to "on", yup you have a problem. The lighting circuit is needed to self-excite the alternator, and the wiring between the alternator and the cluster is the first suspect, since the "bulb" is actually an LED that rarely burns out.

How fast does an car's alternator spin? | AnandTech Forums: Technology.

If the alternator just does not turn with the belt on and the engine running, the belt is too loose. You normally immediately notice that since it's accompanied by a loud squeel. So either you applied the belt way to loose, or not even over the crank pulley. This answer reserved by the author for Quora+ subscribers Access Bart Kranenburg. Measuring across your crank pulley, you get 6 inches. And your alternator pulley is 2 1/2 inches in diameter. Six divided by two and a half equals a 2.4:1 ratio. This means for every time the. Joined Aug 13, 2009. 420 Posts. #5 · Aug 4, 2011. Alternator should be spinning when the engine spin because it is connected by the pulley and belt -unlike A/C compressor it has a magnetic clutch. During ignition, the battery is powering the car. The alternator starts to give power when the engine already started.

Why would an alternator pulley turn freely by hand and not turn... - Quora.

Alternators rarely have full voltage at idle. Some a little more, some a little less. With the car off, turn your headlights on for 1/2 minute. Wait 10 minutes and check the battery voltage. Aroung 12.5 is good. Start the car, check you idle voltage, and also when revved up to 2000 RPM or so. It should be 14.5 or so at 2k. Divide your alternator pulley size into your crank pulley size to get the ratio. Example: If you have a 6" crank pulley and a 2" alternator pulley. 6/2=3. You have a 3 to one ratio, you multiply your engine RPM by 3 so if your engine is turning 1500 RPM's your alternator is turning 4500 RPM's. Note: you do not count the diameter of the other.

Alternator wont spin | Jeep Enthusiast Forums.

If your pulley is okay, then the most likely culprit is the voltage regulator that bolts onto the back of the alternator. Once you remove the back cover, you'll find four torx screws holding the voltage regulator on. The Bosch number for the VR is F00M346089 (BMW 12317561939). There have been a bunch of different Bosch part numbers that have. Step 1 - Check the Alternator Gauge. The first step in monitoring your alternator to check the levels is to check the alternator gauge itself. If you have a voltage gauge, it will show the alternator output for you, and it will be easy to read and see the levels. Power the engine at least 2,000 RPMs for testing purposes.

If your alternator pulley won’t spin, it doesn’t necessarily mean the alternator is bad. You might be surprised how easy it is to clean it up and get everyth. Answer (1 of 4): If you are referring to a standard automotive alternator that is unplugged and does not have a belt coupling it with the rest of the engine, then quite freely.

Wind Spinner Troubleshooting - Wind Spinner won't Spin Fix.

The alternator is self regulating so it doesnt need the third pin and the low voltage system is controlled by the computer on your truck, IIRC. So, if you convert to the AD244 you should only need the same 2 pins connected. They are labled P, L, F or I, and S. S=Sense, used for sensing voltage in a different location such as your fuse block. Your going to have to rewire it acording to the link I gave you the alternator doesn't have one in it if it's the factory one.... Dodge Dana 60 with free spin hubs, Dana 70, B&M Mega shifter, DAP 5x12 VCO's 96 F350 SC dually zf5, 4x4, 92 Cummins, THD 5x12's, THD fuel pin, THD HVLP with adjustable fuel pressure mod, WM, h1c 60/60/12cm WG wired. If the alternator has external fans it can spin while removing and you may hurt yourself. Now if the pulley nut has the standard right hand threads rotate in an anticlockwise direction for removal if not then rotate clockwise with a ½ drive impact wrench or 15/16 socket while keeping your eyes at the alternator.

New Alternator Not Charging Battery - Why Is This The Case?.

The simplified difference is an alternator is a device that converts mechanical energy into alternating current (AC) electrical energy. A generator is a mechanical device that converts mechanical energy into either alternating current (AC) or direct current (DC) electrical energy. Alternators produce more power than generators. Alternator will essentially not spin at all by hand freely, the belt was slipping and howling over it. I removed the belt to verify I could not turn the alt pulley by hand. All belts are / were correctly tensioned btw. I had done a timing belt 2 years / 12k back and everything had been smooth since then.

SOLVED: Changed alternator, cant get belt on, pulley wont - Fixya.

Discussion Starter · #9 · Dec 17, 2014. Sorry about the confusion. The 35 amp alternator uses a different regulator and yes the regulator is a separate unit, not built in to the alternator. When you do the upgrade you must get the regulator and 3 wiring harnesses to adapt it over. The check you are performing is to hopefully prevent the belt from slipping, causing premature wear and failure, and potentially the loss of some or all of the electric production; or jumping off altogether. Best way to check is by trying to spin the alternator pulley. If you cannot spin it inside the belt without great effort, you are ok. You should check these components by removing the alternator cover and making sure that the alternator/engine will engage and spin the ring gear if turned backwards (clockwise) but if turned forward (CCW) the ball clutch should disengage and allow the engine to spin without rotating the ring gear.

What does the alternator belt do? - Pilots of America.

The alternator belt (also known as the serpentine belt) passes through several pulleys on the engine. When the crank turns, the belt pulls the other pulleys and causes them to spin, including the alternator pulley. Naturally, the friction caused by spinning through so many pulleys at high speeds will eventually wear the belt out. Rather, the simple reason why an alternator that is free without the belt being installed can spin freely has to do with the lack of restriction on such an alternator. Without installing the belt, the alternator has no frictional force to hold it back from spinning freely, however, once the belt is installed, the belt becomes the link connecting the alternator to the”.

Does your water pump impeller spin freely? | ST1300 Related.

With the key on 12 volts go to the bulb, the green wire provides ground when the alternator is not charging so the bulb is on. The 12 volts coming through the bulb excites the alternator to start charging, once the alternator starts charging the green wire is no longer a ground it has 12 volts so the warning light is off.
